Yes, Toronto is a modern city that is often described as "so clean" and "friendly". It's the financial center of Canada, it has a vibrant downtown that is alive day and night, a wonderful waterfront along Lake Ontario, lush green parks, and bike paths to get you anywhere.
There are the Toronto Islands which, in addition to offering many activities, give you a spectacular view of the city at sunset, and, of course, tourist attractions like the CN Tower, the Ontario Science Centre, Ripley's Aquarium, the Art Gallery of Ontario, and the Royal Ontario Museum. But there's so much more.
In my opinion the "so much more" comes from the fact that about half of Toronto's population was not born in Canada. In a city of almost 3 million people, that's significant and has a rich, exciting impact in terms of the food you can taste, the neighborhoods you can explore, and the comfort level of just about anyone visiting from anywhere. I'm not saying that Toronto has it all sorted; there are many challenges to be faced as there are in any large city.
Toronto's diversity is one of its greatest features. And though it can be expensive, like any large city, enjoying the diversity is not. If you know your way around, there are plenty of affordable things to do.
Walking is the Best! Free walking tour. Take a free Walking Tour of Downtown. This walk goes from Union Station (Toronto's rail terminus) to City Hall. In bad weather it follows the underground PATH system.
Walk Toronto's neighborhoods. From Little Italy to Little India, from Baby Point to the Beach, there are fascinating neighborhoods to walk throughout Toronto.
Go to Canada's first Urban National Park. Located in the east end of the city, The Rouge is Toronto's largest park and Canada's first Urban National Park. It stretches from the Oak Ridges Moraine to the shores of Lake Ontario covering over 40 square kilometers and Canada's largest wetland. Great hiking.
Go to the Beach. This is a neighborhood along Toronto east waterfront. Enjoy a stroll along this 3 km boardwalk in both the summer and winter. Take the 501 Queen Streetcar east to Beech Avenue, grab a coffee at the local family owned Remarkable Bean and walk south to the lake and boardwalk.
Go swimming or catch some rays. There are 11 designated swimming beaches in Toronto with Blue Flag certification indicating that they meet this international eco-label's high standards for water quality, environmental management, environmental education, safety and services.
Explore Harbourfront. Harbourfront at Lake Ontario is directly south of downtown by a few city blocks and festival central during the spring, summer, and fall. Yes, there are festivals throughout the city but there is always something going on at Harbourfront.
Go to the market. There are a variety of markets in Toronto. St. Lawrence Market was rated the number 1 market in the world by National Geographic. But there is also the Evergreen Brickworks that has a farmer's market, nature walks, classes, cafe, and gardens. A free shuttle bus runs from outside Broadview Subway Station to Evergreen daily. Another favorite of ours is Kensington Market which is a community as much as it is a market. It includes vintage clothing stores, local coffee shops, as well as great food.
